Thepolysilocarb precursor formulations can contain, for example, one ormore functionalized silicon polymers, other polymers, non-silicon basedcross linking agents, monomers, as well as, potentially otheringredients, such as for example, inhibitors, catalysts, initiators,modifiers, dopants, fillers, reinforcers and combinations and variationsof these and other materials and additives. Silicon oxycarbidematerials, SiOC compositions, and similar such terms, unlessspecifically stated otherwise, refer to polysilocarb materials, andwould include liquid materials, solid uncured materials, curedmaterials, and ceramic materials.

Examples of PDCs, PDC formulations and starting materials, are found inU.S. patent application Ser. No. 14/212,896 (issued as U.S. Pat. No.9,815,952), Ser. No. 14/268,150 (issued as U.S. Pat.

The curing segment can be any of the systems, processes and materialsdisclosed and taught in this specification, as well as, those disclosedand taught in U.S. patent application Ser. No. 14/212,896 (issued asU.S. Pat. No. 9,815,952), Ser. No. 14/268,150 (issued as U.S. Pat. No.9,815,943), Ser. No. 14/324,056 (issued as U.S. Pat. No. 9,828,542),Ser. Nos. 14/514,257, 61/946,598 and 62/055,397 and 62/106,094, theentire disclosure of each of which are incorporated herein by reference.

The pyrolizing segment can be any of the systems, processes andmaterials disclosed and taught in this specification, as well as, thosedisclosed and taught in U.S. patent application Ser. No. 14/212,896(issued as U.S. Pat. No. 9,815,952), Ser. No. 14/268,150 (issued as U.S.Pat. No. 9,815,943), Ser. No. 14/324,056 (issued as U.S. Pat. No.9,828,542), Ser. Nos. 14/514,257, 61/946,598 and 62/055,397 and62/106,094, the entire disclosure of each of which are incorporatedherein by reference. By way of example, furnaces can that can be usedfor the pyrolizing segment include, among others: RF furnaces, Microwavefurnaces, pressure furnaces, fluid bed furnaces, box furnaces, tubefurnaces, crystal-growth furnaces, arc melt furnaces, inductionfurnaces, kilns, MoSi₂ heating element furnaces, gas-fired furnaces,carbon furnaces, and vacuum furnaces.

The post-processing segment can involve any type of further processingactivities to enhance, effect, or modify the performance, handleability,processability, features, size, surface properties, and combinations andvariations of these. Thus, for example, the post-processing step caninvolve a grinding step in which the PDC is reduced in size to diametersof less than about 10 μm, less than about 5 μm, less than about 1 μm,less than about 0.5 μm, and less than about 0.1 μm. The PDC can beground, for example, by the use of a ball mill, an attrition mill, arotor stator mill, a hammer mill, a jet-mill, a roller mill, a beadmill, a media mill, a grinder, a homogenizer, a two-plate mill, a doughmixer, and other types of grinding, milling and processing apparatus.The post-processing segment can involve, for example, an agglomeration,where smaller PDC particles are combined to form larger particles,preferably agglomerated particles having diameters of at least about 2μm, at least about 2.5 μm, greater than 2.5 μm, at least about 3 μm, atleast about 5 μm, at least about 10 μm, greater than 10 μm, and greaterthan 12 μm. Preferably, the agglomerated particles are sufficientlybound, or held together, to prevent the particles from falling off,e.g., separating from, the agglomeration during handling, shipping,storage, and processing, e.g., “handling strength.” More preferably, thestrength of the agglomerations is only slightly greater than thehandling strength, and in this manner can readily be broken apart intothe smaller particles for use in a PDC material formulation. Forexample, the agglomeration can have a strength, e.g., crush strength,that is less than about 1/2000 of the strength of the smaller particles,e.g., primary particles, that form the agglomeration, less than about1/500 of the strength of the smaller particles, less than about 1/75 ofthe strength of the smaller particles, and less than ½ of the strengthof the smaller particles. The agglomeration can, for example, be formedby using spray drying techniques. Suitable binders, including forexample sizing agents, for use in spray drying techniques include forexample: dispersants, surfactants, soaps, copolymers, starches, naturaland synthetic polymers and saccharides, lipids, fatty acids,petroleum-derived polymers and oligomers. Sodium alginate, corn starch,potato starch, and other naturally derived starches, fructoses,sucroses, dextroses and other naturally or synthetically derivedsaccharides and sugars, polylactic acid and other naturally derivedpolymers, cellulosic byproducts, carrageenan and other natural products,poly vinyl acetate and other water-soluble polymers, wetting anddispersing agents such as polyacrylates, polyethylene oxides,polypropylene oxides, and copolymers containing them. Parrafins andother waxes, other petrochemical derivatives and petroleum basedpolymers. Surfactants such as Tween, Span, Brij, and other types ofsurfactants; Stearates, oleates, and other modified oils; linearcopolymers, branched copolymers, star polymers and copolymers,hyperbranched polymers and copolymers, comb-like polymers, andcombinations and variations of these.

The amount of binder used to PDC can range from about 0.01% to 5%, about0.1% to about 2%, and preferably less than about 1% and less than about0.5%. Agglomerates can also be formed by batch evaporation and casting,thin film evaporation, wiped-film evaporation, tray drying, oven drying,freeze drying, and other suitable evaporation methods, aggregationtechniques such as sedimentation, solvent exchange and coagulation, pinmixing, filtration, and others, preferably combined with a dryingtechnique, and combinations and variations of these. Further, processingmay involve the application of a surface treatment, wash, or coating tothe surface of the PDC particles to provide predetermined features tothe PDCs, such as for example, enhanced antistatic, wettability,material formulation compatibility, mixability, etc. It should be notedthat while surface treatments are contemplated by the present inventionsto further enhance, e.g., specialize the PDC particles for a particularpurpose; an advantage of the present inventions is the feature that theyare more readily mixed, added, or compiled into material formations,e.g., paints, plastics, inks, coating and adhesives, than the prior artblack pigments, e.g., carbon black ((ASTM Color Index) CI Black 1,6,7)or graphite (CI Black 10) or metal oxides and mixed metal oxides,including but not limited to iron oxides (CI Black 11) and ManganeseIron oxide (CI Black 26) or Iron Manganese oxide (CI Black 33),Manganese oxide (CI Black 14), Copper oxide (CI Black 13), CopperManganese Iron oxide (CI Black 26) or Copper Chrome oxide (CI Black 28),and pigment made by ashing organic matter (CI Black 8, 9) whichtypically for many applications require surface treatments. Thus, anadvantage of the present inventions, among other things, is the abilityto use untreated PDC particles, e.g., no surface treatments, inmaterials formulation.

In the formulation segment, the making of the PDC material formulationtakes place. Thus, for example, the PDC ceramic is mixed into, added to,or otherwise combined with the materials used to make up the materialformulation. Generally, an agglomerate easily breaks down into itsprimary particles, e.g., the primary party state; and the primaryparticles are uniformly and smoothly distributed or suspended in theprimary formulation material, which can be obtained in less than 60minutes of mixing, less than 30 minutes of mixing and quicker.Typically, the PDC ceramic is much more easily mixed into the materialformulation than carbon black to a fully dispersed state. For example,and by way of illustration, PDC ceramic can be easily and quickly mixedwithin 10 minutes into a vessel in which a simple 3 blade stirrer ismixing at 1,000 rpm tip speed. The resin, PDC Ceramic mixture will befully dispersed which is illustrated by a reading of greater than 7 onthe Hegman gauge. The Hegman gauge is a calibrated device to quicklyshow how fine a dispersion is made. A carbon black or oxide blackpigment mixed into the resin in the same manner would produce a Hegmanreading of less than 1 which indicates very large particles still in theresin, because these pigments require high energy milling to break upthe aggregates in the ‘as supplied’ pigment. Generally, the PDC ceramiccan be mixed into, added to, or otherwise combined with the materialformulation in the same manner, using the same or existing equipment,that are present for use with other black pigments or colorants.Preferably, for many applications less expensive, quicker, moreefficient equipment and much less expensive processes than are neededfor carbon black can be used with the PDC particles.

In the application segment the PDC containing material formulation isapplied to an end product, or a component that may be used in an endproduct. The PDC containing material formulation can typically, andpreferably, be applied using the same types of techniques that are usedfor carbon black based formulations, e.g., brush, spray, dip, etc.Moreover, the PDC containing material formulations have applications,and the ability to be applied, in manners that could not be accomplishedwith a similar carbon black based formulation.

It should be understood that the various segments of the embodiment ofFIG. 1 can be combined (e.g., a single piece of equipment could performone of more of the operations of different segments, such as curing andpyrolizing), conducted serially, conducted in parallel, conductedmultiple times, omitted (e.g., post-processing many not be necessary orrequired), conducted in a step wise or batch process (included where thesegments are at different locations, separated by time, e.g., a fewhours, a few days, months or longer, and both), conducted continuously,and in different orders and combinations and variations of these. Thus,for example the post-processing segment of grinding can be performed onthe cured material prior to pyrolysis, and can also be performed on boththe cured and pyrolized materials.

FIGS. 2A and 2B, are SEPMs of an embodiment of a polysilocarb derivedceramic pigment having a primary particle size of 3 μm D₅₀, that wasmade by curing and pyrolizing the polysilocarb precursor formulationinto a monolithic block, and then breaking down that block into primaryparticles. FIGS. 3A and 3B are SEPMs of agglomerates formed by spraydrying 0.5 μm D₅₀ primary particles, which were obtained by furthermilling of the 3.0 μm primary particles shown in FIGS. 2A and 2B.

FIGS. 4A, 4B and 4C, are SEPMs of 1.5 μm D₅₀ primary particles of anembodiment of a polysilocarb derived ceramic pigment, that were formedby a liquid-liquid system. (Liquid-liquid systems are described and setforth in detail in U.S. Patent Application Ser. No. 62/106,094, theentire disclosure of which is incorporated herein by reference) andgenerally involve the formation of a drop of precursor material inanother liquid, and would include for example solution polymerizationtype systems, emulsion polymerization type systems, nano-emulsionformation type systems, and the like.) FIGS. 5A and 5B are SEPMs of theprimary particles of FIGS. 4A and 4B that have been further milled downto 0.9 μm D₅₀.

An embodiment of a polysilocarb ceramic pigment is a colorant suitableand advantageous in multiple fields such as industrial, architectural,marine and automotive systems. The polysilocarb ceramic pigment canpreferably easily disperses into acrylics, lacquers, alkyds, latex,Polyurethane, phenolics, epoxies and waterborne systems providing adurable, uniform coating and pleasant aesthetics in all types offinishes, e.g., matte and gloss.

The polysilocarb ceramic pigment can preferably be low dusting. Thepolysilocarb ceramic pigment does not typically accumulate charge, it iseasy to clean up, and does not cling to surfaces. The polysilocarbceramic pigment is considerably easier to clean up, and control dustingthan typical carbon black. It is theorized that the typical carbonblack's strong hydrophobicity, light particle weight, and very smallparticle size (e.g., 50 nm to 200 nm), among other things, makes carbonblack much more difficult to clean up and control than the polysilocarbceramic pigment. As such, it is preferably a non-sticking, non-clingingblack pigment. These, among other features, are a significantimprovement over carbon black, which is typically difficult to clean up,dusts, and clings to surfaces.

The polysilocarb ceramic pigment can have low oil absorption, leading tolower viscosities, which among other things, permits formulations tomove to higher solids loading with lower VOC content. This pigment canhave a diameter, for example, from about 0.1 μm to 300 μm, from about 1μm to about 150 μm, less than 10 μm, less than 1 μm, less than 0.3 μm,and less than or equal to 0.1 μm.

An embodiment of a batch of the polysilocarb pigment, can have narrow ortight particle size (e.g., diameter) distribution. Thus, embodiments ofthese black ceramic pigments are particles that are within at least 90%of the targeted size, at least 95% of the targeted size, and at least99% of the targeted size. For example, the patch of particles, can havesize distributions such as at least about 90% of their size within a 10μm range, at least about 95% of their size within a 10 μm range, atleast about 98% of their size within a 10 μm range, and at least about99% of their size within a 10 μm range. Further, and for example, theprocess can produce particles each of which can have at least about 90%of their size within a 5 μm range, at least about 95% of their sizewithin a 5 μm range, at least about 98% of their size within a 5 μmrange, and at least about 99% of their size within a 5 μm range.Further, and in submicron particle sized, for example, the process canproduce particles each of which can have at least about 90% of theirsize within a 0.2 μm range, at least about 95% of their size within a0.2 μm range, at least about 98% of their size within a 0.2 μm range,and at least about 99% of their size within a 0.2 μm range. Morepreferably, in sub micron sizes, embodiments these percentage tolerancescan be for the 0.1 μm range, and the 0.05 μm range. Preferably, theselevels of uniformity in the production of the particles are obtainedwithout the need for filtering, sorting or screening the particles.

It should further be noted that preferably these size distributions arefor particles, as used in the formulation. Thus, these particle sizedistributions can be agglomerated, and then upon de-agglomeration andpreferably will have the same, substantially the same particle sizedistribution. In this manner, preferably the particle size, and sizedistribution after de-agglomeration are predictable and predetermined.

In a preferred embodiment the polysilocarb pigments is a blacknon-conductive, acid and alkali resistant, and thermally stable up toabout 300° C., up to about 400° C. and up to about 500° C., or greater.In other embodiments the conductive properties of the pigment can bemodified with additives and fillers, during the making of the pigment,and in this way providing a pigment that is conductive, and has apredetermined conductivity. The color and jetness of these blackpolysilocarb pigments is typically a function of the particle size. In apreferred embodiment of the polysilocarb pigment, mass-tone and tintstrength can be comparable to, and in a further preferred embodiment canbe superior to, current black pigments, e.g., carbon, carbonaceous, andoxide based black pigments. In preferred embodiments the polysilocarbpigments are non-hazardous, having no toxicological effects.

Embodiments of the black polysilocarb pigments can be used in, amongother things, spray, brush-on and power coatings for applications onessentially all metal, ceramic and plastic surfaces in the industrial,marine, architectural, graphic arts & inks, and automotive fields.Embodiments of these pigments further can find applications incosmetics, nail polish, food packaging, and pharmaceutical applicationsand fields, to name a few.

Embodiments of the black polymer derived ceramic pigments are easilydispersed in most media. The black polysilocarb pigments are easily andreadily dispersed in most types of media, basis, resins and carriers.For example, HDPE, LDPE, PP, Acrylic, Epoxy, Linseed Oil, PU, PUR, EPDM,SBR, PVC, water based acrylic emulsions, ABS, SAN, SEBS, SBS, PVDF,PVDC, PMMA, PES, PET, NBR, PTFE, siloxanes, polyisoprene and naturalrubbers, and combinations of these and others.

Embodiments of the black polymer derived ceramic pigments have very lowoil absorption. The oil absorption for polysilocarb ceramic pigments canbe less than about 50 (grams linseed oil per 100 grams of pigment, i.e.g/100 g), less than about 30 g/100 g, and less than about 15 g/100 g. Onthe other hand, typical specialty carbon black pigments have oilabsorptions ranging from about 150 g/100 g to more than 200 g/100 g.Thus, embodiments of the present black polysilocarb ceramic pigments canhave oil absorptions that are at least 13×, 5× or 3× lower than carbonblack pigments having the same or similar blackness.

Embodiments of the black polymer derived ceramic pigments can find usein many applications and industries. For example, the polysilocarbderived ceramic pigments provide high temperature resistancecapabilities, they are indoor/outdoor color fast, UV resistant, and areresistant to most chemicals, finding applications in harsh environments,such as marine and oil field environments. They are non-corrosive andnon-conductive, which enables uses beyond that which most black pigmentscould be utilized. These uses would include Industrial and residentialfurnace coatings; engine components as high heat resistant plastic partsor coatings on metal parts; pipe coatings; chemical plant equipmentcoatings; oil field coatings; residential barbeques; aftermarketcoatings; ceramic and glass inkjet inks; electronic coatings; batteryanodes; gun barrel coatings; PVC siding, metal roof coatings; colorationof ceramic parts for many end uses; space craft coatings; sand coatings;microwave curable elastomers, plastics, inks and coatings; cookware;hotplates; satellite components; high heat absorbing coatings;proprietary military coatings; high heat resistant potting compound;electrical insulation; Fluoropolymer elastomers for use as seals andgaskets in extremely harsh environments; high emissivity coatings,thermal protection systems, thermal barrier coatings, thermal imagingcoatings, injection-molded parts, thermoformed parts, transfer moldedparts, compression molded parts, rotational molded parts, blow-moldedparts, cast parts, vacuum formed parts, hot-isostatic pressed parts,sinterable parts, vacuum impregnated parts, impregnated fiber forms,woven fabrics, textiles, engineering textiles, woven fiber fabrics,fiber mats, wear resistant metal matrix composites, wear resistantceramic matrix composites, wear resistant polymer matrix composites,mixed oxide ceramics, refractory applications, and combinations andvariations of these and others.

Embodiments of the black polymer derived ceramic pigments are microwavesafe, e.g., they do not absorb and are not effect by microwaves. Typicalcarbon black pigments, are effected by microwaves, and cannot be used inmicrowave environments or applications.

In an embodiment of a process to make polymer derived ceramic pigment,and preferably to make a black polymer derived ceramic pigment, in themake-up segment a precursor formulation is metered into a one cubicmeter tank having an in-line mix at rate of about 0.22 cubic meters perhour along with a stream of the catalyst at a ratio of 1 part catalystto 100 parts precursor. The in-line mix tank is equipped with a highspeed mixer. Residence time in the mix tank is about twenty-fiveminutes. The polymerization reaction starts in the mix tank.

In this embodiment of the process, the forming and curing segments arecombined. Thus, the catalyzed precursor formulation, after mixing, iscontinuously feed to a drum, or a moving belt, e.g., a flaker belt, andpreferably a stainless steel flaker belt or other similar device.Nozzles, a drip trough, an elongated opening, or slice, or othermetering and distribution apparatus can be used to preferably obtain auniform distribution, including thickness, of the liquid precursor onthe moving belt. When the precursor is laid down onto the belt, theprecursor can be moving at the same speed as the belt, at a faster speedthan the belt (e.g., rushed), or at a slower speed than the belt (e.g.,dragged). As the liquid precursor is moved with the belt it is heated toa sufficient temperature to cure the precursor formulation to form acured material. For example, radiant heaters may be use above the belt,tunnel dryers may be used, the belt itself may be heated, e.g., withsteam or electric heaters, and combinations and variations of these andother apparatus and methods to heat and maintain the temperature of theprecursor material being carried on the belt. For example, in apreferred embodiment the belt is heated to about 100-200° C. by a steamcoil along the underside of the belt. The cross linking reaction, whichfirst began in the mixing tank, continues as the precursor travels alongthe belt to the point that it solidifies, preferably the precursor hasreached a predetermined and predicted cure amount, e.g., green cure,hard cure, final cure, by the time it reaches the end of the belt.Depending upon the precursor formulation, the amount of catalyst, thetemperature and other factors, the residence time on the belt can beabout 5 to about 60 minutes, more than about 10 minutes, more than about20 minutes, about 20 minutes, and more than about 40 minutes, andgreater and lesser durations.

In this embodiment, at the end of the belt, the cured precursor, e.g.,green material, falls from the belt and into a chopper, which reducesthe size of the green material to about 0 μm, about 100 μm, about 200μm, and about 500 μm, as well as other sizes. The chopped cured materialcan be stored, in for example a storage hopper.

In this embodiment of the process, in the pyrolizing segment the polymerfrom the storage hopper is transferred to cars and fed to a furnace,e.g., a kiln, periodic (e.g., box) kiln, and preferably an oxygendeficient, natural gas fired tunnel kiln. The kiln is operated in anoxygen deficient regime to maintain a non-oxidizing atmosphere in thepolymer. The cars move through the kiln, preferably at a constant rate,which results in a three phase, 24-hour pyrolysis process, e.g., areforming process. In the first phase, the temperature of the polymer israised to 1000° C. over a period of 16 hours. At the end of the 16-hourramp period, it remains at this temperature, 1000° C., for two hours. Inthe final phase the material is air cooled to ambient temperature overthe next six hours. Through this pyrolizing segment of the process thecured material, e.g., green material, is converted to a ceramicmaterial. The ceramic material is removed, e.g., dumped from the kilncars into an intermediate storage hopper awaiting further processing.

In this embodiment of the processes, throughout the pyrolizing segment,the exhaust gases from the kiln are preferably ducted away to a cleaningor waste handling system, for example to a Vapor Destruction Unit (VDU)to destroy residual combustibles. The VDU can than be followed by othercleaning systems, such as for example, a wet scrubber to remove anyparticulates (predominately silica). The silica can then be removed fromthe water effluent and recovered for reuse, sale or proper disposal.After removal of the silica, the effluent from the scrubber can bereused for example in a grey water loop, further cleaned and reused, ortransferred to a waste water treatment facility for eventual discard.

In this embodiment of the process, in the post-processing segment threepost processing techniques are used—jet milling, bead milling and spraydrying. In many embodiments of applications for polymer derived ceramicpigments, and in particular for black polymer derived ceramic pigments,a particular particle size can be a factor, an application requirement,and in some instances a very important parameter for the pigment. Inthis embodiment, jet milling is the first stage of the size reductionprocess. Ceramic material having a particle size of about 300-500 μm, istaken from the intermediate storage; and is fed into the jet millingreceiver. At the jet milling receiver the ceramic material is directedto several, e.g., two, three, four or more, parallel mills. The jetmills reduce the particle size from 300-500 μm, to about 1-20 μm, about3 μm, and about 2 μm. The use of steam jet milling can reduce theparticle size to about 1 μm, less than about 1 μm and about 0.5 μm andpotentially smaller, these reductions in size can preferably be achievedun-surface treated, i.e., with out the need to provide a surfacetreatment to the larger particles prior to milling. The milled ceramiccan then be classified and those sizes not meeting the requirements forfurther processing can be removed and preferably repurposed. Forexample, about 10% of the product can be classified and sold at anintermediate size.

The remaining 90% of the jet mill product is transferred to the beadmill receiver for further size reduction. The 1-20 μm jet milled productis fed to a slurry tank where it is mixed with a liquid phase orsolvent, such as demineralized water, and a dispersant at a ratio ofapproximately 60 parts solids, 39 parts solvent and 1 part dispersant.The dispersant can be a soap, detergent, surfactant, fatty acid, naturaloil, synthetic oil, wetting agent, dispersing agent, natural andsynthetic oils, natural and synthetic glycols and polyglycols, modifiedwaxes and hydrocarbons. Dispersants function to stabilize the particlevia either steric, electrosteric, or electrostatic means and can benon-ionic, anionic, cationic, or zwitterionic. Structures can be linearpolymers and copolymers, head-tail type modified polymers andcopolymers, AB-block copolymers, ABA block copolymers, branched blockcopolymers, gradient copolymers, branched gradient copolymers,hyperbranched polymers and copolymers, star polymers and copolymers.BASF, Lubrizol, RT Vanderbilt, and BYK are all common manufacturers ofdispersants. Trade names include: Lubrizol Solsperse series, VanderbiltDarvan series, BASF Dispex series BYK DisperByk series, BYK LP-C 2XXXXseries. Grades can include BYK DisperByk 162, 181, 182, 190, 193, 2200,and 2152; LP-C 22091, 22092, 22116, 22118, 22120, 22121, 22124, 22125,22126, 22131, 22134, 22136, 22141, 22146, 22147, 22435; LP-N 22269;Solsperse 3000, Darvan C—N. A proper dispersant will provide goodreduction in viscosity from a high-solids content paste with <5%additive, causing it to become a flowable liquid instead of anon-flowable paste. The ratio of dispersant to ceramic solids can rangefrom about 0.01 wt % to 8 wt %, to 0.5 wt % to 4 wt %, 1 wt % to 3 wt %,and greater and lesser ratios. This slurry is fed, e.g., batch wise,semi-continuous or continuously, to single, to several parallel,two-stage bead milling systems, e.g., two, three, four, five or more.These mills may also have other mills serially connected to theiroutputs. Bead milling further reduces the particle size to less than 1μm, and preferably for submicron applications to a particle size ofabout 0.1 μm.

In this embodiment the wet product from the bead is fed to a spraydryer, which can be steam heated, gas heated, air, inert gas, orelectrically heated, where the water content is reduced to <1 percent.In the spray dryer, the 0.1 μm particles agglomerate to a 10-80 μmparticle size, e.g., agglomerate size, agglomerated particle size.Preferably, a batch, lot, or shipment of the agglomerate particles has amedian particle size distribution, e.g., D₅₀, of greater than about 10μm, greater than about 20 μm, and greater than about 50 μm. Preferablythese agglomerates are stable through the handling and shipping processand the unpacking and initial use for an application. In addition to thepreferred median particle size distribution of greater than 10 μm, themean agglomerate particle size may be from 10 μm or less, from about 10μm to about 80 μm, and may be larger than 80 μm.

In this embodiment the exhaust from the spray dryer goes through acyclone, followed by a bag filter to remove any particulates prior torelease to the atmosphere. The collected dust is recycled to the beadmill or spray dryer feed. The water or solvent evaporated from thepowder in the spray dryer is condensed, recovered and recycled to thebead mill feed slurry. The dry product from the spray dryer can bestored, packaged, shipped to users, or further processed or treated.

For an embodiment of the product that is a dry powder,or dry agglomerate, the moisture content can be from about 0% to about10% moisture, about less than 5%, about less than 3%, and about lessthan 1%.

In the foregoing embodiment of a process to make polymer derived ceramicpigment, a preferable embodiment of the polymer derived ceramic pigmentis a black polysilocarb derived ceramic pigment. The black polysilocarbderived pigment can be used in many applications.

Polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments have applications in, for example,coatings used on, or in, walls, appliances, automobiles, engines, pipes,grills, microwaves, cook wear, wires, printed circuit boards, human andanimal nails, cosmetics, pipes, interior of components such asautomobile components, food packaging and other devices, structurescomponents and articles. They have applications in coatings that provideend use features, such as for example, corrosion protection, abrasionprotection, skid resistance, decorative and astatic effects,photosensitive properties, UV protection, heat resistance andprotection, and combinations and variations of these and other features.They have applications in coating that are organic, inorganic andcombinations of these. They have applications in coatings that areporcelain, enamels, electroplated, to name a few others. They haveapplications in architectural coating, product coatings used by originalequipment manufacturers (“OEM coatings”), special purpose coatings andother types of coatings. Architectural coatings would include forexample paints and varnishes. Product coatings would include OEMcoatings, industrial coatings, industrial finishes, boats, water craft,ships, after market coatings, and repair/refurbishing coatings, theproducts to which product coatings are applied is essentially endless,and would include for example automobiles, aircraft, appliances, wire,pipes, furniture, metal cans, chewing gum wrappers, packaging,equipment, etc. Specialty coatings would include for example, specialtycoatings for cars, specialty marine coatings, stripping for highways,and others.

Polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments have applications in coatingsembodiments that contain a binder, volatile components, a pigment (whichmay be solely one or more polymer derived black ceramic pigments orcombinations of the polymer derived black pigment and other pigments),and additives (noting that the polymer derived pigment, which may beother colors than black and preferably embodiments of polysilocarbpigments, which may be other colors than black, can function as, or are,additives). These pigments are used with all types of resin, includingacrylics, alkyds, amino, cellulosics, epoxies, polyesters, urethanes,poly(vinyl acetates), poly(vinyl chlorides), and others.

The polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments can have surface properties andsizes such that they do not change the rheology of existing formulationsthat use other types of black pigments. In this manner they can bedirectly substituted for some, or all of the other type of pigment in aparticular formulation without changing the rheology of that formulationand providing for example improved blackness and opacity. The nature ofthese pigments also provides the ability to have an embodiment of thesepigments that provides functionality to control, modify, and regulatethe rheology of a formulation. In this manner these pigments would havea dual role in the formulation as a pigment and as a rheology controladditive.

Embodiments of coatings containing black polysilocarb derived ceramicpigments provided enhanced abrasion resistance, e.g., the wearing awayof a surface, and enhanced mar resistance, e.g., disturbances in thesurface that alters its appearance. Abrasion and mar resistance wouldinclude resistance to scratching, gouging, wearing, and generally theresistance to the detrimental effects that occur when two surfaces arein sliding contact. Coatings using the black polysilocarb derivedceramic pigments have abrasion resistance as measured by Taber AbrasionTester (reported as number of mg of coating worn off after 1,000 cycles)of at most 30 mg, at most 150 mg, from about 10 mg to about 200 mg, andgreater than 200 mg.

Embodiment of coatings containing black polysilocarb derived ceramicpigments provided enhanced hardness. Hardness for coatings typically ismeasured by way of indentations, scratch, and pendulum tests. Hardnesstests for coatings typically include an indentation test, the fallingball indentation Test (ASTM D-2394, which is well known to and availableto the art, and the entire disclosure of which is incorporated herein byreference), a scratch test, the pencil hardness test (ASTM-D-3363-00,which is well known to and available to the art, and the entiredisclosure of which is incorporated herein by reference), and a pendulumtest, the Sward rocker (ASTM-2134-93), which is well known to andavailable to the art, and the entire disclosure of which is incorporatedherein by reference).

Embodiment of Coatings using the black polysilocarb derived ceramicpigments have indentation test results of at least 100 inch pounds atleast 160 inch pounds, from about 50 to about 150 inch pounds, andgreater than 160 inch pounds. Coatings using the black polysilocarbderived ceramic pigments can have the same or better blackness, whilehaving increases in indentation test results of at least about 50 inchpounds, at least about 160 inch pounds, and greater, when compared to asimilar formulation using carbon black or metal oxides as the pigment.

Embodiments of coatings using the black polysilocarb derived ceramicpigments have scratch test results of at least 7B pencil, at least Fpencil, from about 8B pencil to about 6H pencil, and greater than 6Hpencil. Coatings using the black polysilocarb derived ceramic pigmentscan have the same or better blackness, while having increases in scratchtest results of at least about 7B pencil, at least about F pencil, andgreater, when compared to a similar formulation using carbon black ormetal oxides as the pigment.

Embodiments of coatings using the black polysilocarb derived ceramicpigments have pendulum test results of at least 20 oscillations at least25 oscillations, from about 15 to about 55 oscillations, and greaterthan 56 oscillations. Coatings using the black polysilocarb derivedceramic pigments can have the same or better blackness, while havingincreases in pendulum test results of at least about 20 oscillations, atleast about 50 oscillations, and greater, when compared to a similarformulation using carbon black or metal oxides as the pigment.

The polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments can be used in formulations havingUV stabilizers. These pigments do not diminish or adversely affect theUV stabilizing ability performance of the UV stabilizers. It istheorized that the polysilocarb derived ceramic pigments may provideadded UV stabilization to these UV stabilized formulations. The UVstabilizers can be UV absorbers, UV quenchers, and combinations ofthese. Typical UV stabilizes include, for example,2-hydroxybenzophenones, 2-(2-hydroxyphenyl)-2H-benztriazoles,2-(2-hydroxyphenyl)-4,6-phenyl-1,3,5-triazines, benzylidenemalonates,oxalanilides and others.

Typically, embodiments of the polymer derived black ceramic pigments,and preferably black polysilocarb derived ceramic pigments can functionas a UV absorber, and can be added to coatings to provide thesefunction, thus function as both a additive and a pigment. Embodiments ofa 3.0 μm D₅₀ black polysilocarb derived ceramic pigment exhibit UVabsorption (e.g., absorption coefficient, e.g., absorptivity) based uponthe UV-vis data taken in diluted DI water solutions, set out in Table 1.The concentration of material is given in grams per 100 g of water(equivalently, g/100 mL). These concentrations gave a translucentsolution.

TABLE 1 absorption coefficient dB/cm/ dB/cm/ dB/cm/ concentrationconcentration concentration concentration (g/100 g) @ 300 nm @ 450 nm @800 nm 0.00952 3538.894732 3526.83657 3451.4463 0.02590 979.6193238961.519095 946.46022

Generally, embodiments of the polysilocarb derived ceramic pigment canhave absorption coefficients of greater than 500 dB/cm/(g/100 g),greater than 5,000 dB/cm/(g/100 g), greater than 10,000 dB/cm/(g/100 g),from about 500 dB/cm/(g/100 g) to about 1,000 dB/cm/(g/100 g), fromabout 1,000 to about 5,000 dB/cm/(g/100 g), and from about 500dB/cm/(g/100 g) to about 10,000 dB/cm/(g/100 g). In general, the smallerthe pigments size, for the same pigment the higher will be theabsorption coefficients.

The polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments can be used in formulations havingantioxidants. These pigments do not diminish or adversely affect theanti-oxidizing performance of the antioxidants. It is theorized that thepolysilocarb derived ceramic pigments may provide added anti-oxidationprotection to these antioxidant containing formulations. Typicalantioxidants include for example preventive antioxidants, peroxidedecomposers, sulfides, phosphites, metal complex agents, and others.

The polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments can be used in formulations havinghinder amine light stabilizers (“HALS”), which function to prevent thephoto oxidative degradation of coatings. These pigments do not diminishor adversely affect the photo-oxidizing performance of the HALS. It istheorized that the polysilocarb derived ceramic pigments may provideadded photo-oxidation protection to these HALS containing formulations.Further, the black polysilocarb derived ceramic pigments in someembodiments can be used to replace some, most, and all, of the HALS inthe coating.

The polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments can be used in many types ofcoating or formulations, such as for example thermoplastic acrylicresins, thermosetting acrylic resins, hydroxy-functional acrylic resins,water reducible thermosetting acrylic resins, waterborne coatings (i.e.,any coating with an aqueous media, e.g., latex coatings), waterreducible coatings (i.e., a waterborne coating based on a resin havinghydrophilic groups in most or all of its molecules), water solublecoatings (i.e., are soluble in water), latexes, acrylic latexes, vinylester latexes, thermosetting latexes, polyester resins,hydroxy-terminated polyester resins, amino resins, aminoplast resins,baked thermosetting coatings, melamine-formaldehyde resins (e.g., classI and class II), urea-formaldehyde resins, benzoguanamine-formaldehyderesins, glycoluril-formaldehyde resins,poly(meth)acrylamide-formaldehyde resins, polyurethane resins, twopackage solvent borne urethane coatings, epoxy resins, waterborneepoxy-amine systems, drying oil based resins, varnishes, alkyd resins,silicones, silicone rubber resins, and tetraethylorthosilicate (TEOS)based resins, among others.

The polymer derived black ceramic pigments, and preferably blackpolysilocarb derived ceramic pigments can be used in many types ofcoating or formulations that utilize different types of solvents, suchas for example, weak hydrogen-bonding solvents (e.g., aliphatic andaromatic hydrocarbons), hydrogen-bond acceptor solvents (e.g., estersand ketones) and hydrogen-bond donor-acceptor solvents (e.g., alcoholsand propylene glycol).

In general, the smaller the particle size, the greater the fraction oflight that will be absorbed by the same quantity, i.e., weight ofparticles. For pigments, and generally for embodiments of the polymerderived black ceramic pigments, and preferably black polysilocarbderived ceramic pigments, the smaller the particle size of the pigmentthe greater the absorption of light.

The ability of a coating to hiding the substrate, i.e., hiding, is aproperty that can be affected by many factors. Generally, hidingincreases as film or coating thickness increases at the same pigmentloading. Lower hiding coatings require thicker films. Also, hidingincreases as pigment particle size decreases until a maximum hiding isreached and then hiding begins to decrease. Two coatings will hide thesubstrate the same, one with a lower pigment loading (of smallerparticle size) and one with a higher pigment loading of a largerparticle size. In general, embodiments of the polymer derived blackceramic pigments, and preferably black polysilocarb derived ceramicpigments, provide higher hiding coatings, or hiding ability, for thesame loading (e.g., weight of pigment to volume of coating) of blackmixed metal oxide pigments and more quickly approach the hiding power offurnace carbon black.

Pigment loading to hiding is the required weight of pigment in a 50micron dry film coating to cover a black and white substrate such thatthe eye cannot differentiate a difference in color over either coloredbackground.

In general, in using the polymer derived black ceramic pigments, andpreferably the black polysilocarb derived ceramic pigments, they can beformulated, mixed or made into a concentrated composition that cantypically, although not necessarily, have other ingredients. Theseconcentrated compositions are typically liquids, although notnecessarily, they typically are call mill bases, dispersions, colorants,master-batches, and similar terms, which terms for the purposes of thisspecification, unless specifically stated otherwise, will be used tointerchangeably. The present black ceramic pigments have excellentwettability, separation properties, and stability properties in bothorganic and aqueous media.

Polymer derived ceramic mill bases can contain one embodiment of thepresent ceramic pigments, several different embodiments of the presentceramic pigments, other types of pigments, such as carbon black, andcombinations and variations of these. When more than one pigment ispresent the mill base can be referred to as a composite grind, orcomposite grind mill base. Thus, for example, an embodiment of a polymerderived ceramic a composite grind mill base has a black polysilocarbceramic pigment and one or more of the following pigments: organicpigments, such as arylamide yellow (PY 73), diarylide yellow, barium red2B toner (PR 48.1); polycyclic pigments, such as copper phthalocyanine,dioxanzine violet (PV 23), tetrachloro thiondigo (PR 88); inorganicpigments, such as carbon black, titanium dioxide, iron oxides, azurite,cadmium sulphides.

Although in embodiments of the present black ceramic pigments,dispersants are not needed or required, they may be added to either themill base, or with the mill base at the time it is added to the coatingformulation. Dispersants such as polymeric dispersants, A-B copolymerdispersants, hyperdispersants, superdispersants, and others may be used.In general dispersants function to stabilize the particle via eithersteric, electrosteric, or electrostatic means and can be non-ionic,anionic, cationic, or zwitterionic. Embodiments of dispersant structurescan be linear polymers and copolymers, head-tail type modified polymersand copolymers, AB-block copolymers, ABA block copolymers, branchedblock copolymers, gradient copolymers, branched gradient copolymers,hyperbranched polymers and copolymers, star polymers and copolymers, andcombinations and various of these and others.

It being understood that the mill base can be prepared and stored forlater use, shipped, or used immediately. Further the step of making amill base may be combined with, a part of, or otherwise incorporatedinto the process of formulation and making the coating. Generally inmaking a polymer derived ceramic pigmented coating three steps typicallymay be used—premixing, e.g., stirring the dry pigment into a liquidvehicle and eliminating any lumps; imparting shear stress to separatethe pigment aggregates, which may be done in the presence of adispersion stabilizer; and, letting down, which entails combining thepigment dispersion, e.g., mill base, with the remainder of theingredients for the coating formulation. It being understood that someequipment is capable of performing only one or two of the steps, whileother are capable of performing all three steps.

Equipment that may be used for forming the mill base can include, forexample, high-speed disk dispersers, rotor-stator mixers, ball mills,basket mills, shot mills, hammer mills, media mills (e.g., sand mills,shot mills, bead mills), three roll mills, two roll mills, extruders,kneaders, internal batch mixers, such as banbury machines, extruders,ultrasound dispersers, and others.

The polymer derived black ceramic pigments, and preferably the blackpolysilocarb derived ceramic pigments can be used to make tinting pastesin this manner providing an embodiment of a polymer derived tintingpaste. In general tinting paste will have a high loading of pigment to asmall amount of resin so that a small amount of paste will give themaximum color. The polymer derived black ceramic pigments, andpreferably the black polysilocarb derived ceramic pigments improve thetint strength as the particle size decreases. In general, tintingembodiments of the polymer derived black ceramic pigments, andpreferably black polysilocarb derived ceramic pigments, provide highertinting strength in coatings, (less black pigment required to reach thesame grey color with a lightness value between 72 and 75 on the CIELABLab scale, the lightness coming from a larger amount of TiO₂ whitepigment which is tinted to a grey color by small additions of the blackpigment). The smaller particle size polymer derived black ceramicpigment has higher tinting strength than black mixed metal oxidepigments and more quickly approaches the tinting strength of furnacecarbon black. Tinting pastes can use multiple black additives, includingpolysilocarb materials.

It should be understood that the use of headings in this specificationis for the purpose of clarity, reference, and is not limiting in anyway. Thus, the processes compositions, and disclosures described under aheading should be read in context with the entirely of thisspecification, including the various examples. The use of headings inthis specification should not limit the scope of protection afford thepresent inventions.

General Processes for Obtaining a Polysilocarb Precursor

Typically polymer derived ceramic precursor formulations, and inparticular polysilocarb precursor formulations can generally be made bythree types of processes, although other processes, and variations andcombinations of these processes may be utilized. These processesgenerally involve combining precursors to form a precursor formulation.One type of process generally involves the mixing together of precursormaterials in preferably a solvent free process with essentially nochemical reactions taking place, e.g., “the mixing process.” The othertype of process generally involves chemical reactions, e.g., “thereaction type process,” to form specific, e.g., custom, precursorformulations, which could be monomers, dimers, trimers and polymers. Athird type of process has a chemical reaction of two or more componentsin a solvent free environment, e.g., “the reaction blending typeprocess.” Generally, in the mixing process essentially all, andpreferably all, of the chemical reactions take place during subsequentprocessing, such as during curing, pyrolysis and both.

It should be understood that these terms—reaction type process, reactionblending type process, and the mixing type process—are used forconvenience and as a short hand reference. These terms are not, andshould not be viewed as, limiting. For example, the reaction process canbe used to create a precursor material that is then used in the mixingprocess with another precursor material.

These process types are described in this specification, among otherplaces, under their respective headings. It should be understood thatthe teachings for one process, under one heading, and the teachings forthe other processes, under the other headings, can be applicable to eachother, as well as, being applicable to other sections, embodiments andteachings in this specification, and vice versa. The starting orprecursor materials for one type of process may be used in the othertype of processes. Further, it should be understood that the processesdescribed under these headings should be read in context with theentirely of this specification, including the various examples andembodiments.

It should be understood that combinations and variations of theseprocesses may be used in reaching a precursor formulation, and inreaching intermediate, end and final products. Depending upon thespecific process and desired features of the product the precursors andstarting materials for one process type can be used in the other. Aformulation from the mixing type process may be used as a precursor, orcomponent in the reaction type process, or the reaction blending typeprocess. Similarly, a formulation from the reaction type process may beused in the mixing type process and the reaction blending process.Similarly, a formulation from the reaction blending type process may beused in the mixing type process and the reaction type process. Thus, andpreferably, the optimum performance and features from the otherprocesses can be combined and utilized to provide a cost effective andefficient process and end product. These processes provide greatflexibility to create custom features for intermediate, end, and finalproducts, and thus, any of these processes, and combinations of them,can provide a specific predetermined product. In selecting which type ofprocess is preferable, factors such as cost, controllability, shelflife, scale up, manufacturing ease, etc., can be considered.

In addition to being commercially available the precursors may be madeby way of an alkoxylation type process, e.g., an ethoxylation process.In this process chlorosilanes are reacted with ethanol in the presencesof a catalysis, e.g., HCl, to provide the precursor materials, whichmaterials may further be reacted to provide longer chain precursors.Other alcohols, e.g., methanol may also be used. Thus, for exampleSiCl₄, SiCl₃H, SiCl₂(CH₃)₂, SiCl₂(CH₃)H, Si(CH₃)₃CI, Si(CH₃)ClH, arereacted with ethanol CH₃CH₂OH to form precursors. In some of thesereactions phenols may be the source of the phenoxy group, which issubstituted for a hydride group that has been placed on the silicon.One, two or more step reactions may need to take place.

Precursor materials may also be obtained by way of an acetylene reactionroute. In general there are several known paths for adding acetylene toSi—H. Thus, for example, tetramethylcyclotetrasiloxane can be reactedwith acetylene in the presence of a catalyst to producetetramethyltetravinylcyclotetrasiloxane. This product can then be ringopened and polymerized in order to form linear vinyl, methylsiloxanes.Alternatively, typical vinyl silanes can be produced by reacting methyl,dichlorosilane (obtained from the direct process or Rochow process) withacetylene. These monomers can then be purified (because there may besome scrambling) to form vinyl, methyl, dichlorosilane. Then the vinylmonomer can be polymerized via hydrolysis to form many cyclic, andlinear siloxanes, having various chain lengths, including for examplevarious cyclotetrasiloxanes (e.g., D₄′) and various cyclopentasiloxanes(e.g., D₅′). These paths, however, are costly, and there has been a longstanding and increasing need for a lower cost raw material source toproduce vinyl silanes. Prior to the present inventions, it was notbelieved that MHF could be used in an acetylene addition process toobtain vinyl silanes. MHF is less expensive than vinyl, methyl (eitherlinear or cyclic), and adding acetylene to MHF to make vinyl meets,among other things, the long standing need to provide a more costeffective material and at relatively inexpensive costs. In making thisaddition the following variables, among others, should be considered andcontrolled: feed (D₄′, linear methyl, hydrogen siloxane fluids);temperature; ratio of acetylene to Si—H; homogeneous catalysts(Karstedt's, DBT Laureate, no catalyst, Karstedt's with inhibitor);supported catalysts (Pt on carbon, Pt on alumina, Pd on alumina); flowrates (liquid feed, acetylene feed); pressure; and, catalystconcentration. Examples of embodiments of reactions providing for theaddition of acetylene to MHF (cyclic and linear) are provided in TablesA and B. Table A are batch acetylene reactions. Table B are continuousacetylene reactions. It should be understood that batch, continuous,counter current flow of MHF and acetylene feeds, continuous recycle ofsingle pass material to achieve higher conversions, and combinations andvariations of these and other processes can be utilized.

Continuous High Pressure Reactor (“CHPR”) embodiments may beadvantageous for, among other reasons: reaction conversion saving moreacetylene needed in liquid phase; tube reactors providing pressureswhich in turn increases solubility of acetylene; reaction with hexynesaving concentration and time (e.g., 100 hours); can eliminatehomogeneous catalyst and thus eliminate hydrosilylation reaction withresultant vinyls once complete; and, using a heterogeneous (Solid)catalyst to maintain product integrity, increased shelf-life, increasepot-life and combinations and variations of these.

In addressing the various conditions in the acetylene additionreactions, some factors may be: crosslinking retardation by dilution,acetylene and lower catalyst concentration; and conversion (usingheterogeneous catalyst) may be lower for larger linear moleculescompared to smaller molecules.

The presence and quality of vinyl and vinyl conversions can bedetermined by, among other things: FT-IR for presence of vinylabsorptions, decrease in SiH absorption; ¹H NMR for presence of vinylsand decrease in SiH; ¹³C NMR for presence of vinyls.

As used herein, unless specified otherwise the terms %, weight % andmass % are used interchangeably and refer to the weight of a firstcomponent as a percentage of the weight of the total, e.g., formulation,mixture, material or product. As used herein, unless specified otherwise“volume %” and “% volume” and similar such terms refer to the volume ofa first component as a percentage of the volume of the total, e.g.,formulation, material or product.

The Mixing Type Process

Precursor materials may be methyl hydrogen, and substituted and modifiedmethyl hydrogens, siloxane backbone additives, reactive monomers,reaction products of a siloxane backbone additive with a silane modifieror an organic modifier, and other similar types of materials, such assilane based materials, silazane based materials, carbosilane basedmaterials, phenol/formaldehyde based materials, and combinations andvariations of these. The precursors are preferably liquids at roomtemperature, although they may be solids that are melted, or that aresoluble in one of the other precursors. (In this situation, however, itshould be understood that when one precursor dissolves another, it isnevertheless not considered to be a “solvent” as that term is used withrespect to the prior art processes that employ non-constituent solvents,e.g., solvents that do not form a part or component of the end product,are treated as waste products, and both.)

The precursors are mixed together in a vessel, preferably at roomtemperature. Preferably, little, and more preferably no solvents, e.g.,water, organic solvents, polar solvents, non-polar solvents, hexane,THF, toluene, are added to this mixture of precursor materials.Preferably, each precursor material is miscible with the others, e.g.,they can be mixed at any relative amounts, or in any proportions, andwill not separate or precipitate. At this point the “precursor mixture”or “polysilocarb precursor formulation” is compete (noting that if onlya single precursor is used the material would simply be a “polysilocarbprecursor” or a “polysilocarb precursor formulation” or a“formulation”). Although complete, fillers and reinforcers may be addedto the formulation. In preferred embodiments of the formulation,essentially no, and more preferably no chemical reactions, e.g.,crosslinking or polymerization, takes place within the formulation, whenthe formulation is mixed, or when the formulation is being held in avessel, on a prepreg, or over a time period, prior to being cured.

The precursors can be mixed under numerous types of atmospheres andconditions, e.g., air, inert, N₂, Argon, flowing gas, static gas,reduced pressure, elevated pressure, ambient pressure, and combinationsand variations of these.

Additionally, inhibitors such as cyclohexane, 1-Ethynyl-1-cyclohexanol(which may be obtained from ALDRICH), Octamethylcyclotetrasiloxane, andtetramethyltetravinylcyclotetrasiloxane, may be added to thepolysilocarb precursor formulation, e.g., an inhibited polysilocarbprecursor formulation. It should be noted thattetramethyltetravinylcyclotetrasiloxane may act as both a reactant and areaction retardant (e.g., an inhibitor), depending upon the amountpresent and temperature, e.g., at room temperature it is a retardant andat elevated temperatures it is a reactant. Other materials, as well, maybe added to the polysilocarb precursor formulation, e.g., a filledpolysilocarb precursor formulation, at this point in processing,including fillers such as SiC powder, carbon black, sand, polymerderived ceramic particles, pigments, particles, nanotubes, whiskers, orother materials, discussed in this specification or otherwise known tothe arts. Further, a formulation with both inhibitors and fillers wouldbe considered an inhibited, filled polysilocarb precursor formulation.

Depending upon the particular precursors and their relative amounts inthe polysilocarb precursor formulation, polysilocarb precursorformulations may have shelf lives at room temperature of greater than 12hours, greater than 1 day, greater than 1 week, greater than 1 month,and for years or more. These precursor formulations may have shelf livesat high temperatures, for example, at about 90° F., of greater than 12hours, greater than 1 day, greater than 1 week, greater than 1 month,and for years or more. The use of inhibitors may further extend theshelf life in time, for higher temperatures, and combinations andvariations of these. The use of inhibitors, may also have benefits inthe development of manufacturing and commercial processes, bycontrolling the rate of reaction, so that it takes place in the desiredand intended parts of the process or manufacturing system.

As used herein the term “shelf life” should be given its broadestpossible meaning, unless specified otherwise, and would include, forexample, the formulation being capable of being used for its intendedpurpose, or performing, e.g., functioning, for its intended use, at 100%percent as well as a freshly made formulation, at least about 90% aswell as a freshly made formulation, at least about 80% as well as afreshly made formulation, and at at least about 70% as well as a freshlymade formulation.

Precursors and precursor formulations are preferably non-hazardousmaterials. They have flash points that are preferably above about 70°C., above about 80° C., above about 100° C. and above about 300° C., andabove. Preferably, they may be noncorrosive. Preferably, they may have alow vapor pressure, may have low or no odor, and may be non- or mildlyirritating to the skin.

A catalyst or initiator may be used, and can be added at the time of,prior to, shortly before, or at an earlier time before the precursorformulation is formed or made into a structure, prior to curing. Thecatalysis assists in, advances, and promotes the curing of the precursorformulation to form a preform.

The time period where the precursor formulation remains useful forcuring after the catalysis is added is referred to as “pot life”, e.g.,how long can the catalyzed formulation remain in its holding vesselbefore it should be used. Depending upon the particular formulation,whether an inhibitor is being used, and if so the amount being used,storage conditions, e.g., temperature, low O₂ atmosphere, andpotentially other factors, precursor formulations can have pot lives,for example, of from about 5 minutes to about 10 days, about 1 day toabout 6 days, about 4 to 5 days, about 30 minutes, about 15 minutes,about 1 hour to about 24 hours, and about 12 hours to about 24 hours.

The catalyst can be any platinum (Pt) based catalyst, which can, forexample, be diluted to a ranges of: about 0.01 parts per million (ppm)Pt to about 250 ppm Pt, about 0.03 ppm Pt, about 0.1 ppm Pt, about 0.2ppm Pt, about 0.5 ppm Pt, about 0.02 to 0.5 ppm Pt, about 1 ppm to 200ppm Pt and preferably, for some applications and embodiments, about 5ppm to 50 ppm Pt. The catalyst can be a peroxide based catalyst with,for example, a 10 hour half life above 90 Cat a concentration of between0.1% to 3% peroxide, and about 0.5% and 2% peroxide. It can be anorganic based peroxide. It can be any organometallic catalyst capable ofreacting with Si—H bonds, Si—OH bonds, or unsaturated carbon bonds,these catalysts may include: dibutyltin dilaurate, zinc octoate,peroxides, organometallic compounds of for example titanium, zirconium,rhodium, iridium, palladium, cobalt or nickel. Catalysts may also be anyother rhodium, rhenium, iridium, palladium, nickel, and ruthenium typeor based catalysts. Combinations and variations of these and othercatalysts may be used. Catalysts may be obtained from ARKEMA under thetrade name LUPEROX, e.g., LUPEROX 231; and from Johnson Matthey underthe trade names: Karstedt's catalyst, Ashby's catalyst, Speier'scatalyst.

Further, custom and specific combinations of these and other catalystsmay be used, such that they are matched to specific formulations, and inthis way selectively and specifically catalyze the reaction of specificconstituents. Moreover, the use of these types of matchedcatalyst-formulations systems may be used to provide predeterminedproduct features, such as for example, pore structures, porosity,densities, density profiles, high purity, ultra high purity, and othermorphologies or features of cured structures and ceramics.

In this mixing type process for making a precursor formulation,preferably chemical reactions or molecular rearrangements only takeplace during the making of the starting materials, the curing process,and in the pyrolizing process. Chemical reactions, e.g.,polymerizations, reductions, condensations, substitutions, take place orare utilized in the making of a starting material or precursor. Inmaking a polysilocarb precursor formulation by the mixing type process,preferably no and essentially no, chemical reactions and molecularrearrangements take place. These embodiments of the present mixing typeprocess, which avoid the need to, and do not, utilize a polymerizationor other reaction during the making of a precursor formulation, providessignificant advantages over prior methods of making polymer derivedceramics. Preferably, in the embodiments of these mixing type offormulations and processes, polymerization, crosslinking or otherchemical reactions take place primarily, preferably essentially, andmore preferably solely during the curing process.

Thus, in additional to the forgoing type of precursors, it iscontemplated that a precursor may be a compound of the following generalformula.

Wherein end cappers E₁ and E₂ are chosen from groups such as trimethylsilicon (—Si(CH₃)₃), dimethyl silicon hydroxy (—Si(CH₃)₂OH), dimethylsilicon hydride (—Si(CH₃)₂H), dimethyl vinyl silicon(—Si(CH₃)₂(CH═CH₂)), (—Si(CH₃)₂(C₆H₅)) and dimethyl alkoxy silicon(—Si(CH₃)₂(OR). The R groups R₁, R₂, R₃, and R₄ may all be different, orone or more may be the same. Thus, for example, R₂ is the same as R₃, R₃is the same as R₄, R₁ and R₂ are different with R₃ and R₄ being thesame, etc. The R groups are chosen from groups such as hydride (—H),methyl (Me)(—C), ethyl (—C—C), vinyl (—C═C), alkyl (—R)(C_(n)H_(2n+1)),allyl (—C—C═C), aryl (′R), phenyl (Ph)(—C₆H₅), methoxy (—O—C), ethoxy(—O—C—C), siloxy (—O—Si—R₃), alkoxy (—O—R), hydroxy (—O—H), phenylethyl(—C—C—C₆H₅) and methyl, phenyl-ethyl (—C—C(—C)(—C₆H₅).

In general, embodiments of formulations for polysilocarb formulationsmay for example have from about 0% to 50% MH, about 20% to about 99% MH,about 0% to about 30% siloxane backbone additives, about 1% to about 60%reactive monomers, about 30% to about 100% TV, and, about 0% to about90% reaction products of a siloxane backbone additives with a silanemodifier or an organic modifier reaction products.

In mixing the formulations sufficient time should be used to permit theprecursors to become effectively mixed and dispersed. Generally, mixingof about 15 minutes to an hour is sufficient. Typically, the precursorformulations are relatively, and essentially, shear insensitive, andthus the type of pumps or mixing are not critical. It is further notedthat in higher viscosity formulations additional mixing time may berequired. The temperature of the formulations, during mixing shouldpreferably be kept below about 45° C., and preferably about 10° C. (Itis noted that these mixing conditions are for the pre-catalyzedformulations.)

The Reaction Type Process

In the reaction type process, in general, a chemical reaction is used tocombine one, two or more precursors, typically in the presence of asolvent, to form a precursor formulation that is essentially made up ofa single polymer that can then be, catalyzed, cured and pyrolized. Thisprocess provides the ability to build custom precursor formulations thatwhen cured can provide plastics having unique and desirable featuressuch as high temperature, flame resistance and retardation, strength andother features. The cured materials can also be pyrolized to formceramics having unique features. The reaction type process allows forthe predetermined balancing of different types of functionality in theend product by selecting functional groups for incorporation into thepolymer that makes up the precursor formulation, e.g., phenyls whichtypically are not used for ceramics but have benefits for providing hightemperature capabilities for plastics, and styrene which typically doesnot provide high temperature features for plastics but provides benefitsfor ceramics.

In general a custom polymer for use as a precursor formulation is madeby reacting precursors in a condensation reaction to form the polymerprecursor formulation. This precursor formulation is then cured into apreform through a hydrolysis reaction. The condensation reaction forms apolymer of the type shown below.

Where R₁ and R₂ in the polymeric units can be a hydride (—H), a methyl(Me)(—C), an ethyl (—C—C), a vinyl (—C═C), an alkyl (—R)(C_(n)H_(2n+1)),an unsaturated alkyl (—C_(n)H_(2n−1)), a cyclic alkyl (—C_(n)H_(2n−1)),an allyl (—C—C═C), a butenyl (—C₄H₇), a pentenyl (—C₅H₉), acyclopentenyl (—C₅H₇), a methyl cyclopentenyl (—C₅H₆(CH₃)), anorbornenyl (—C_(X)H_(Y), where X=7-15 and Y=9-18), an aryl (′R), aphenyl (Ph)(—C₆H₅), a cycloheptenyl (—C₇H₁₁), a cyclooctenyl (—C₈H₁₃),an ethoxy (—O—C—C), a siloxy (—O—Si—R₃), a methoxy (—O—C), an alkoxy,(—O—R), a hydroxy, (—O—H), a phenylethyl (—C—C—C₆H₅) a methyl,phenyl-ethyl (—C—C(—C)(—C₆H₅)) and a vinylphenyl-ethyl(—C—C(C₆H₄(—C═C))). R₁ and R₂ may be the same or different. The customprecursor polymers can have several different polymeric units, e.g., A₁,A₂, A_(n), and may include as many as 10, 20 or more units, or it maycontain only a single unit, for example, MHF made by the reactionprocess may have only a single unit.

Embodiments may include precursors, which include among others, atriethoxy methyl silane, a diethoxy methyl phenyl silane, a diethoxymethyl hydride silane, a diethoxy methyl vinyl silane, a dimethyl ethoxyvinyl silane, a diethoxy dimethyl silane. an ethoxy dimethyl phenylsilane, a diethoxy dihydride silane, a triethoxy phenyl silane, adiethoxy hydride trimethyl siloxane, a diethoxy methyl trimethylsiloxane, a trimethyl ethoxy silane, a diphenyl diethoxy silane, adimethyl ethoxy hydride siloxane, and combinations and variations ofthese and other precursors, including other precursors set forth in thisspecification.

The end units, Si End 1 and Si End 2, can come from the precursors ofdimethyl ethoxy vinyl silane, ethoxy dimethyl phenyl silane, andtrimethyl ethoxy silane. Additionally, if the polymerization process isproperly controlled a hydroxy end cap can be obtained from theprecursors used to provide the repeating units of the polymer.

In general, the precursors are added to a vessel with ethanol (or othermaterial to absorb heat, e.g., to provide thermal mass), an excess ofwater, and hydrochloric acid (or other proton source). This mixture isheated until it reaches its activation energy, after which the reactiontypically is exothermic. Generally, in this reaction the water reactswith an ethoxy group of the silicon of the precursor monomer, forming ahydroxy (with ethanol as the byproduct). Once formed this hydroxybecomes subject to reaction with an ethoxy group on the silicon ofanother precursor monomer, resulting in a polymerization reaction. Thispolymerization reaction is continued until the desired chain length(s)is built.

Control factors for determining chain length, among others, are: themonomers chosen (generally, the smaller the monomers the more that canbe added before they begin to coil around and bond to themselves); theamount and point in the reaction where end cappers are introduced; andthe amount of water and the rate of addition, among others. Thus, thechain lengths can be from about 180 mw (viscosity about 5 cps) to about65,000 mw (viscosity of about 10,000 cps), greater than about 1000 mw,greater than about 10,000 mw, greater than about 50,000 mw and greater.Further, the polymerized precursor formulation may, and typically does,have polymers of different molecular weights, which can be predeterminedto provide formulation, cured, and ceramic product performance features.

Upon completion of the polymerization reaction the material istransferred into a separation apparatus, e.g., a separation funnel,which has an amount of deionized water that, for example, is from about1.2× to about 1.5× the mass of the material. This mixture is vigorouslystirred for about less than 1 minute and preferably from about 5 to 30seconds. Once stirred the material is allowed to settle and separate,which may take from about 1 to 2 hours. The polymer is the higherdensity material and is removed from the vessel. This removed polymer isthen dried by either warming in a shallow tray at 90° C. for about twohours; or, preferably, is passed through a wiped film distillationapparatus, to remove any residual water and ethanol. Alternatively,sodium bicarbonate sufficient to buffer the aqueous layer to a pH ofabout 4 to about 7 is added. It is further understood that other, andcommercial, manners of mixing, reacting and separating the polymer fromthe material may be employed.

Preferably a catalyst is used in the curing process of the polymerprecursor formulations from the reaction type process. The samepolymers, as used for curing the precursor formulations from the mixingtype process can be used. It is noted that, generally unlike the mixingtype formulations, a catalyst is not necessarily required to cure areaction type polymer. Inhibitors may also be used. However, if acatalyst is not used, reaction time and rates will be slower. The curingand the pyrolysis of the cured material from the reaction process isessentially the same as the curing and pyrolysis of the cured materialfrom the mixing process and the reaction blending process.

The reaction type process can be conducted under numerous types ofatmospheres and conditions, e.g., air, inert, N₂, Argon, flowing gas,static gas, reduced pressure, ambient pressure, elevated pressure, andcombinations and variations of these.

The Reaction Blending Type Process

In the reaction blending type process precursor are reacted to from aprecursor formulation, in the absence of a solvent.

For example, an embodiment of a reaction blending type process has aprecursor formulation that is prepared from MHF and Dicyclopentadiene(“DCPD”). Using the reactive blending process a MHF/DCPD polymer iscreated and this polymer is used as a precursor formulation. (It can beused alone to form a cured or pyrolized product, or as a precursor inthe mixing or reaction processes.) MHF of known molecular weight andhydride equivalent mass; “P01” (P01 is a 2% Pt(0)tetravinylcyclotetrasiloxane complex (e.g.,tetramethyltetravinylcyclotetrasiloxane) intetravinylcyclotetrasiloxane, diluted 20× withtetravinylcyclotetrasiloxane to 0.1% of Pt(0) complex. In this manner 10ppm Pt is provided for every 1% loading of bulk cat.) catalyst 0.20 wt %of MHF starting material (with known active equivalent weight), from 40to 90%; and Dicyclopentadiene with >83% purity, from 10 to 60% areutilized. In an embodiment of the process, a sealable reaction vessel,with a mixer, can be used for the reaction. The reaction is conducted inthe sealed vessel, in air; although other types of atmosphere can beutilized. Preferably, the reaction is conducted at atmospheric pressure,but higher and lower pressures can be utilized. Additionally, thereaction blending type process can be conducted under numerous types ofatmospheres and conditions, e.g., air, inert, N₂, Argon, flowing gas,static gas, reduced pressure, ambient pressure, elevated pressure, andcombinations and variations of these.

In an embodiment, 850 grams of MHF (85% of total polymer mixture) isadded to reaction vessel and heated to about 50° C. Once thistemperature is reached the heater is turned off, and 0.20% by weight P01Platinum catalyst is added to the MHF in the reaction vessel. Typically,upon addition of the catalyst bubbles will form and temp will initiallyrise approximately 2-20° C.

When the temperature begins to fall, about 150 g of DCPD (15 wt % oftotal polymer mixture) is added to the reaction vessel. The temperaturemay drop an additional amount, e.g., around 5-7° C.

At this point in the reaction process the temperature of the reactionvessel is controlled to, maintain a predetermined temperature profileover time, and to manage the temperature increase that may beaccompanied by an exotherm. Preferably, the temperature of the reactionvessel is regulated, monitored and controlled throughout the process.

In an embodiment of the MHF/DCPD embodiment of the reaction process, thetemperature profile can be as follows: let temperature reach about 80°C. (may take ˜15-40 min, depending upon the amount of materialspresent); temperature will then increase and peak at ˜104° C., as soonas temperature begins to drop, the heater set temperature is increasedto 100° C. and the temperature of the reaction mixture is monitored toensure the polymer temp stays above 80° C. for a minimum total of about2 hours and a maximum total of about 4 hours. After 2-4 hours above 80°C., the heater is turned off, and the polymer is cooled to ambient. Itbeing understood that in larger and smaller batches, continuous,semi-continuous, and other type processes the temperature and timeprofile may be different.

In larger scale, and commercial operations, batch, continuous, andcombinations of these, may be used. Industrial factory automation andcontrol systems can be utilized to control the reaction, temperatureprofiles and other processes during the reaction.

In the above table, the “degree of polymerization” is the number ofmonomer units, or repeat units, that are attached together to form thepolymer. “Equivalents _/mol” refers to the molar equivalents.“Grams/mole of vinyl” refers to the amount of a given polymer needed toprovide 1 molar equivalent of vinyl functionality. “VMH” refers tomethyl vinyl fluid, a linear vinyl material from the ethoxy process,which can be a substitute for TV. The numbers “0200” etc. for VT are theviscosity in centipoise for that particular VT.

Curing and Pyrolysis

Precursor formulations, including the polysilocarb precursorformulations from the above types of processes, as well as others, canbe cured to form a solid, semi-sold, or plastic like material.Typically, the precursor formulations are spread, shaped, or otherwiseformed into a preform, which would include any volumetric structure, orshape, including thin and thick films. In curing, the polysilocarbprecursor formulation may be processed through an initial cure, toprovide a partially cured material, which may also be referred to, forexample, as a preform, green material, or green cure (not implyinganything about the material's color). The green material may then befurther cured. Thus, one or more curing steps may be used. The materialmay be “end cured,” i.e., being cured to that point at which thematerial has the necessary physical strength and other properties forits intended purpose. The amount of curing may be to a final cure (or“hard cure”), i.e., that point at which all, or essentially all, of thechemical reaction has stopped (as measured, for example, by the absenceof reactive groups in the material, or the leveling off of the decreasein reactive groups over time). Thus, the material may be cured tovarying degrees, depending upon its intended use and purpose. Forexample, in some situations the end cure and the hard cure may be thesame. Curing conditions such as atmosphere and temperature may affectthe composition of the cured material.

In making the precursor formulation into a structure, or preform, theprecursor formulation, e.g., polysilocarb formulation, can be, forexample, formed using the following techniques: spraying, spray drying,atomization, nebulization, phase change separation, flowing, thermalspraying, drawing, dripping, forming droplets in liquid andliquid-surfactant systems, painting, molding, forming, extruding,spinning, ultrasound, vibrating, solution polymerization, emulsionpolymerization, micro-emulsion polymerization, injecting, injectionmolding, or otherwise manipulated into essentially any volumetric shape.These volumetric shapes may include for example, the following: spheres,pellets, rings, lenses, disks, panels, cones, frustoconical shapes,squares, rectangles, trusses, angles, channels, hollow sealed chambers,hollow spheres, blocks, sheets, coatings, films, skins, particulates,beams, rods, angles, slabs, columns, fibers, staple fibers, tubes, cups,pipes, and combinations and various of these and other more complexshapes, both engineering and architectural.

The forming step, the curing steps, and the pyrolysis steps may beconducted in batch processes, serially, continuously, with time delays(e.g., material is stored or held between steps), and combinations andvariations of these and other types of processing sequences. Further,the precursors can be partially cured, or the cure process can beinitiated and on going, prior to the precursor being formed into avolumetric shape. These steps, and their various combinations may be,and in some embodiments preferably are, conducted under controlled andpredetermined conditions (e.g., the material is exposed to apredetermined atmosphere, and temperature profile during the entirely ofits processing, e.g., reduced oxygen, temperature of cured preform heldat about 140° C. prior to pyrolysis). It should be further understoodthat the system, equipment, or processing steps, for forming, curing andpyrolizing may be the same equipment, continuous equipment, batch andlinked equipment, and combinations and variations of these and othertypes of industrial processes. Thus, for example, a spray dryingtechnique could form cured particles that are feed directly into afluidized bed reactor for pyrolysis.

The polysilocarb precursor formulations can be made into neat,non-reinforced, non-filled, composite, reinforced, and filledstructures, intermediates, end products, and combinations and variationsof these and other compositional types of materials. Further, thesestructures, intermediates and end products can be cured (e.g., greencured, end cured, or hard cured), uncured, pyrolized to a ceramic, andcombinations and variations of these (e.g., a cured material may befilled with pyrolized material derived from the same polysilocarb as thecured material).

The precursor formulations may be used to form a “neat” material, (by“neat” material it is meant that all, and essentially all of thestructure is made from the precursor material or unfilled formulation;and thus, there are no fillers or reinforcements).

The polysilocarb precursor formulations may be used to coat orimpregnate a woven or non-woven fabric, made from for example carbonfiber, glass fibers or fibers made from a polysilocarb precursorformulation (the same or different formulation), to from a prepregmaterial. Thus, the polysilocarb precursor formulations may be used toform composite materials, e.g., reinforced products. For example, theformulation may be flowed into, impregnated into, absorbed by orotherwise combined with a reinforcing material, such as carbon fibers,glass fiber, woven fabric, grapheme, carbon nanotubes, thin films,precipitates, sand, non-woven fabric, copped fibers, fibers, rope,braided structures, ceramic powders, glass powders, carbon powders,graphite powders, ceramic fibers, metal powders, carbide pellets orcomponents, staple fibers, tow, nanostructures of the above, polymerderived ceramics, any other material that meets the temperaturerequirements of the process and end product, and combinations andvariations of these. The reinforcing material may also be made from, orderived from the same material as the formulation that has been formedinto a fiber and pyrolized into a ceramic, or it may be made from adifferent precursor formulation material, which has been formed into afiber and pyrolized into a ceramic.

The polysilocarb precursor formulation may be used to form a filledmaterial. A filled material would be any material having other solid, orsemi-solid, materials added to the polysilocarb precursor formulation.The filler material may be selected to provide certain features to thecured product, the ceramic product and both. These features may relateto, or be, for example, aesthetic, tactile, thermal, density, radiation,chemical, cost, magnetic, electric, and combinations and variations ofthese and other features. These features may be in addition to strength.Thus, the filler material may not affect the strength of the cured orceramic material, it may add strength, or could even reduce strength insome situations. The filler material could impart color, magneticcapabilities, fire resistances, flame retardance, heat resistance,electrical conductivity, anti-static, optical properties (e.g.,reflectivity, refractivity and iridescence), aesthetic properties (suchas stone like appearance in building products), chemical resistivity,corrosion resistance, wear resistance, reduced cost, abrasionsresistance, thermal insulation, UV stability, UV protective, and otherfeatures that may be desirable, necessary, and both, in the end productor material. Thus, filler materials could include carbon black, copperlead wires, thermal conductive fillers, electrically conductive fillers,lead, optical fibers, ceramic colorants, pigments, oxides, sand, dyes,powders, ceramic fines, polymer derived ceramic particles, pore-formers,carbosilanes, silanes, silazanes, silicon carbide, carbosilazanes,siloxane, powders, ceramic powders, metals, metal complexes, carbon,tow, fibers, staple fibers, boron containing materials, milled fibers,glass, glass fiber, fiber glass, and nanostructures (includingnanostructures of the forgoing) to name a few.

The polysilocarb formulation and products derived or made from thatformulation may have metals and metal complexes. Filled materials wouldinclude reinforced materials. In many cases, cured, as well as pyrolizedpolysilocarb filled materials can be viewed as composite materials.Generally, under this view, the polysilocarb would constitute the bulkor matrix phase, (e.g., a continuous, or substantially continuousphase), and the filler would constitute the dispersed (e.g.,non-continuous), phase. Depending upon the particular application,product or end use, the filler can be evenly distributed in theprecursor formulation, unevenly distributed, distributed over apredetermined and controlled distribution gradient (such as from apredetermined rate of settling), and can have different amounts indifferent formulations, which can then be formed into a product having apredetermined amounts of filler in predetermined areas (e.g., striatedlayers having different filler concentration). It should be noted,however, that by referring to a material as “filled” or “reinforced” itdoes not imply that the majority (either by weight, volume, or both) ofthat material is the polysilcocarb. Thus, generally, the ratio (eitherweight or volume) of polysilocarb to filler material could be from about0.1:99.9 to 99.9:0.1.

The polysilocarb precursor formulations may be used to formnon-reinforced materials, which are materials that are made ofprimarily, essentially, and preferably only from the precursormaterials; but may also include formulations having fillers or additivesthat do not impart strength.

The curing may be done at standard ambient temperature and pressure(“SATP”, 1 atmosphere, 25° C.), at temperatures above or below thattemperature, at pressures above or below that pressure, and over varyingtime periods. The curing can be conducted over various heatings, rate ofheating, and temperature profiles (e.g., hold times and temperatures,continuous temperature change, cycled temperature change, e.g., heatingfollowed by maintaining, cooling, reheating, etc.). The time for thecuring can be from a few seconds (e.g., less than about 1 second, lessthan 5 seconds), to less than a minute, to minutes, to hours, to days(or potentially longer). The curing may also be conducted in any type ofsurrounding environment, including for example, gas, liquid, air, water,surfactant containing liquid, inert atmospheres, N₂, Argon, flowing gas(e.g., sweep gas), static gas, reduced O₂, reduced pressure, elevatedpressure, ambient pressure, controlled partial pressure and combinationsand variations of these and other processing conditions. For high puritymaterials, the furnace, containers, handling equipment, atmosphere, andother components of the curing apparatus and process are clean,essentially free from, and do not contribute any elements or materials,that would be considered impurities or contaminants, to the curedmaterial. In an embodiment, the curing environment, e.g., the furnace,the atmosphere, the container and combinations and variations of thesecan have materials that contribute to or effect, for example, thecomposition, catalysis, stoichiometry, features, performance andcombinations and variations of these in the preform, the ceramic and thefinal applications or products.

Preferably, in embodiments of the curing process, the curing takes placeat temperatures in the range of from about 5° C. or more, from about 20°C. to about 250° C., from about 20° C. to about 150° C., from about 75°C. to about 125° C., and from about 80° C. to 90° C. Although higher andlower temperatures and various heating profiles, (e.g., rate oftemperature change over time (“ramp rate”, e.g., A degrees/time), holdtimes, and temperatures) can be utilized.

The cure conditions, e.g., temperature, time, ramp rate, may bedependent upon, and in some embodiments can be predetermined, in wholeor in part, by the formulation to match, for example the size of thepreform, the shape of the preform, or the mold holding the preform toprevent stress cracking, off gassing, or other phenomena associated withthe curing process. Further, the curing conditions may be such as totake advantage of, preferably in a controlled manner, what may havepreviously been perceived as problems associated with the curingprocess. Thus, for example, off gassing may be used to create a foammaterial having either open or closed structure. Similarly, curingconditions can be used to create or control the microstructure and thenanostructure of the material. In general, the curing conditions can beused to affect, control or modify the kinetics and thermodynamics of theprocess, which can affect morphology, performance, features andfunctions, among other things.

Upon curing the polysilocarb precursor formulation a cross linkingreaction takes place that provides in some embodiments a cross-linkedstructure having, among other things, an —R₁—Si—C—C—Si—O—Si—C—C—Si—R₂—where R₁ and R₂ vary depending upon, and are based upon, the precursorsused in the formulation. In an embodiment of the cured materials theymay have a cross-linked structure having 3-coordinated silicon centersto another silicon atom, being separated by fewer than 5 atoms betweensilicons.

During the curing process some formulations may exhibit an exotherm,i.e., a self heating reaction, that can produce a small amount of heatto assist or drive the curing reaction, or that may produce a largeamount of heat that may need to be managed and removed in order to avoidproblems, such as stress fractures. During the cure off gassingtypically occurs and results in a loss of material, which loss isdefined generally by the amount of material remaining, e.g., cure yield.Embodiments of the formulations, cure conditions, and polysilocarbprecursor formulations of embodiments of the present inventions can havecure yields of at least about 90%, about 92%, about 100%. In fact, withair cures the materials may have cure yields above 100%, e.g., about101-105%, as a result of oxygen being absorbed from the air.Additionally, during curing the material typically shrinks, thisshrinkage may be, depending upon the formulation, cure conditions, andthe nature of the preform shape, and whether the preform is reinforced,filled, neat or unreinforced, from about 20%, less than 20%, less thanabout 15%, less than about 5%, less than about 1%, less than about 0.5%,less than about 0.25% and smaller.

Curing of the preform may be accomplished by any type of heatingapparatus, or mechanisms, techniques, or morphologies that has therequisite level of temperature and environmental control, for example,heated water baths, electric furnaces, microwaves, gas furnaces,furnaces, forced heated air, towers, spray drying, falling filmreactors, fluidized bed reactors, lasers, indirect heating elements,direct heating, infrared heating, UV irradiation, RF furnace, in-situduring emulsification via high shear mixing, in-situ duringemulsification via ultrasonication.

The cured preforms, either unreinforced, neat, filled or reinforced, maybe used as a stand alone product, an end product, a final product, or apreliminary product for which later machining or processing may beperformed on. The preforms may also be subject to pyrolysis, whichconverts the preform material into a ceramic.

In pyrolizing the preform, or cured structure, or cured material, it isheated to about 600° C. to about 2,300° C.; from about 650° C. to about1,200° C., from about 800° C. to about 1300° C., from about 900° C. toabout 1200° C. and from about 950° C. to 1150° C. At these temperaturestypically all organic structures are either removed or combined with theinorganic constituents to form a ceramic. Typically at temperatures inthe about 650° C. to 1,200° C. range the resulting material is anamorphous glassy ceramic. When heated above about 1,200° C. the materialtypically may from nano crystalline structures, or micro crystallinestructures, such as SiC, Si3N₄, SiCN, β SiC, and above 1,900° C. an aSiC structure may form, and at and above 2,200° C. a SiC is typicallyformed. The pyrolized, e.g., ceramic materials can be single crystal,polycrystalline, amorphous, and combinations, variations and subgroupsof these and other types of morphologies.

The pyrolysis may be conducted under many different heating andenvironmental conditions, which preferably include thermo control,kinetic control and combinations and variations of these, among otherthings. For example, the pyrolysis may have various heating ramp rates,heating cycles and environmental conditions. In some embodiments, thetemperature may be raised, and held a predetermined temperature, toassist with known transitions (e.g., gassing, volatilization, molecularrearrangements, etc.) and then elevated to the next hold temperaturecorresponding to the next known transition. The pyrolysis may take placein reducing atmospheres, oxidative atmospheres, low O₂, gas rich (e.g.,within or directly adjacent to a flame), inert, N₂, Argon, air, reducedpressure, ambient pressure, elevated pressure, flowing gas (e.g., sweepgas, having a flow rate for example of from about from about 15.0 GHSVto about 0.1 GHSV, from about 6.3 GHSV to about 3.1 GHSV, and at about3.9 GHSV), static gas, and combinations and variations of these.

The pyrolysis is conducted over a time period that preferably results inthe complete pyrolysis of the preform. For high purity materials, thefurnace, containers, handling equipment, and other components of thepyrolysis apparatus are clean, essentially free from, free from and donot contribute any elements or materials, that would be consideredimpurities or contaminants, to the pyrolized material. A constant flowrate of “sweeping” gas can help purge the furnace during volatilegeneration. In an embodiment, the pyrolysis environment, e.g., thefurnace, the atmosphere, the container and combinations and variationsof these, can have materials that contribute to or effect, for example,the composition, stoichiometry, features, performance and combinationsand variations of these in the ceramic and the final applications orproducts.

During pyrolysis material may be lost through off gassing. The amount ofmaterial remaining at the end of a pyrolysis step, or cycle, is referredto as char yield (or pyrolysis yield). The formulations and polysilocarbprecursor formulations of embodiments of the present formulations canhave char yields for SiOC formation of at least about 60%, about 70%,about 80%, and at least about 90%, at least about 91% and greater. Infact, with air pyrolysis the materials may have char yields well above91%, which can approach 100%. In order to avoid the degradation of thematerial in an air pyrolysis (noting that typically pyrolysis isconducted in inert atmospheres, reduced oxygen atmosphere, essentiallyinert atmosphere, minimal oxygen atmospheres, and combinations andvariations of these) specifically tailored formulations can be used. Forexample, formulations high in phenyl content (at least about 11%, andpreferably at least about 20% by weight phenyls), formulations high inallyl content (at least about 15% to about 60%) can be used for airpyrolysis to mitigate the degradation of the material.

The initial or first pyrolysis step for SiOC formation, in someembodiments and for some uses, generally yields a structure that is notvery dense, and for example, may not reached the density required forits intended use. However, in some examples, such as the use oflightweight spheres, proppants, pigments, and others, the firstpyrolysis may be, and is typically sufficient. Thus, generally areinfiltration process may be performed on the pyrolized material, toadd in additional polysilocarb precursor formulation material, to fillin, or fill, the voids and spaces in the structure. This reinfiltratedmaterial may then be cured and repyrolized. (In some embodiments, thereinfiltrated materials is cured, but not pyrolized.) This process ofpyrolization, reinfiltration may be repeated, through one, two, three,and up to 10 or more times to obtain the desired density of the finalproduct.

In some embodiments, upon pyrolization, graphenic, graphitic, amorphouscarbon structures and combinations and variations of these are presentin the Si—O—C ceramic. A distribution of silicon species, consisting ofSiOxCy structures, which result in SiO4, SiO3C, SiO2C2, SiOC3, and SiC4are formed in varying ratios, arising from the precursor choice andtheir processing history. Carbon is generally bound between neighboringcarbons and/or to a Silicon atom. In general, in the ceramic state,carbon is largely not coordinated to an oxygen atom, thus oxygen islargely coordinated to silicon

The pyrolysis may be conducted in any heating apparatus that maintainsthe request temperature and environmental controls. Thus, for examplepyrolysis may be done with gas fired furnaces, electric furnaces, directheating, indirect heating, fluidized beds, kilns, tunnel kilns, boxkilns, shuttle kilns, coking type apparatus, lasers, microwaves, andcombinations and variations of these and other heating apparatus andsystems that can obtain the request temperatures for pyrolysis.

Custom and predetermined control of when chemical reactions,arrangements and rearrangements, occur in the various stages of theprocess from raw material to final end product can provide for reducedcosts, increased process control, increased reliability, increasedefficiency, enhanced product features, increased purity, andcombinations and variation of these and other benefits. The sequencingof when these transformations take place can be based upon theprocessing or making of precursors, and the processing or making ofprecursor formulations; and may also be based upon cure and pyrolysisconditions. Further, the custom and predetermined selection of thesesteps, formulations and conditions, can provide enhanced product andprocessing features through the various transformations, e.g., chemicalreactions; molecular arrangements and rearrangements; and microstructurearrangements and rearrangements.

At various points during the manufacturing process, the polymer derivedceramic structures, e.g., polysilocarb structures, intermediates and endproducts, and combinations and variations of these, may be machined,milled, molded, shaped, drilled, etched, or otherwise mechanicallyprocessed and shaped.

For example: 300-500micron range beads; 350 (+/−5%) micron beads; 5-15 micron range powder.Particle size ranges for a particular polysilocarb ceramic pigmentpreferably range as tight as +/−10% and more preferably +/−5%. The rangemay also be broader in certain applications, e.g., 100-1000 for beads,and e.g., 0.5-100 for powders. The density and hardness of thepolysilocarb ceramic pigment can be varied, controlled and predeterminedby the precursor formulations used, as well as the curing and pyrolizingconditions. The polysilocarb ceramic pigments can provided enhancedcorrosion resistance, scratch resistance and color (UV) stability topaint formulations. Optical properties or effects of the polysilocarbceramic pigment can, among other ways, be controlled by the use ofdifferent gases and gas mixtures, as well as other curing and pyrolysisconditions. The polysilocarb ceramic pigment loading can be usedanywhere from a 1% to a 40% in order to achieve the desired effect.Further, the use of the polysilocarb ceramic pigments can provideenhanced flame retardant benefits. The polysilocarb ceramic pigmentshave a further advantage of being low dusting, and easily mixed into anytype of paint formulations, e.g., latex, enamel, polyurethanes,automotive OEM and refinish, alkyd, waterborne, acrylic and polyolcoatings formulations. The polysilocarb ceramic pigments can also beused as a fine colorant in inks and graphic arts formulations.
